AddEntry for multiple sets : IndexOutOfBoundsException: Index: 0, Size: 0

[pwireless]

Library Release 3.0.3

Defining:

private static final int SET1 = 0; private static final int SET2 = 1; private static final int SET3 = 2; private static final int SET4 = 3;

and the following basic addEntry function :

private void addEntry(LineChart mChart, int set_index) {

    LineData data = mChart.getData();

    if (data != null) {

        ILineDataSet set = data.getDataSetByIndex(set_index);
        // set.addEntry(...); // can be called as well

        if (set == null) {
            set = createSet(set_index);
            data.addDataSet(set);
        }

        switch (set_index) {
            case SET1:
                data.addEntry(new Entry(set.getEntryCount(), ((float) (Math.random() * 40) + 80f)), set_index);
                break;
            case SET2:
                data.addEntry(new Entry(set.getEntryCount(), ((float) (Math.random() * 40) + 90f)), set_index);
                break;
            case SET3:
                data.addEntry(new Entry(set.getEntryCount(), ((float) (Math.random() * 40) + 100f)), set_index);
                break;
            case SET4:
                data.addEntry(new Entry(set.getEntryCount(), ((float) (Math.random() * 40) + 110f)), set_index);
                break;
        }
        data.notifyDataChanged();

        // let the chart know it's data has changed
        mChart.notifyDataSetChanged();

        // limit the number of visible entries
        //mChart.setVisibleXRangeMaximum(120);

        // move to the latest entry
        mChart.moveViewToX(data.getEntryCount());
    }
}

Now if I call :

addEntry(mChart, SET1); addEntry(mChart, SET2); addEntry(mChart, SET3);

note, in this case I add entry to 0, 1, 2 sets.

It works fine.

If I call :

addEntry(mChart, SET1); addEntry(mChart, SET3); addEntry(mChart, SET4);

note, in this case I add entry to 0, 2, 3 sets.

then I get this crash :

Since this is a duplicate of multiple other issues (all in that reference to the pull request) I'm going to close it.

Glad that after my issue clarification, the long issue was solved... Thank you
